摘要：
Four new coordination compounds, [Zn(dba)(bpy)] (n) (1), {[Zn(dba)(phen)]center dot 2H(2)O} (n) (2), [Cd(dba)(bpy)(H2O)(2)] (3) and [Cd-2(dba)(2)(phen)(2)] (n) (4) (H(2)dba = 2,5-dihydroxy-p-benzenediacetic acid, bpy = 2,2'-bipyridine, phen = 1,10-phenanthroline) have been prepared via solvothermal method and characterized by single-crystal X-ray diffraction, infrared spectroscopy, elemental analysis and powder X-ray diffraction. 1 and 2 possess 1D infinite chain structures. Complex 3 exhibits a mononuclear structure. Complex 4 owns binuclear symmetry units, which were bridged via the dba ligands forming a 2D framework. The fluorescence properties of 1-4 have been studied.
